NCT ID: NCT03012919 Completed - Feasibility Clinical Trials

Evaluation of an Active Decision Support System for Hemodynamic Optimization During High Risk Vascular Surgery

Start date: February 2015
Phase: N/A
Study type: Interventional

Rivers et al. laid the foundation for modern hemodynamic and fluid management by establishing goal directed therapy (GDT) for the treatment of sepsis using fluid and inotropic and vasoactive agents. There have been many subsequent protocols to improve outcome in the operating room or in the ICU. These are mainly passive decision support systems. Active clinical decision support systems using fluid and pharmacologic agents to improve intraoperative hemodynamics are not really found. The investigators developed an active clinical decision support system based on an institutional GDT-protocol using fluid, vasopressors and inotropes using the LiDCOrapid device. The goal of the study was to check the feasibility of an active clinical decision support system to optimize hemodynamics during high risk vascular surgery based on the principles of GDT implementing fluid, vasopressors and inotropes.

NCT ID: NCT01398059 Completed - Feasibility Clinical Trials

The Metabolic Effects of Breaks in Sedentary Time

Start date: July 2011
Phase: N/A
Study type: Interventional

The purpose of this study is to determine whether acute bouts of sedentary behaviour (with or without breaks and/or structured physical activity) result in measurable changes in metabolic health in children and youth.

NCT ID: NCT00557869 Completed - Feasibility Clinical Trials

Optimization of Cardiac-MR Protocols

Start date: October 2002
Phase: N/A
Study type: Observational

The aim of the present study is the optimization of various magnetic resonance (MR) investigation protocols of the heart and the lung without contrast agent application as well as the generation of normal values from cardiac MR images. One of the main problems in cardiac MR investigations is the strong dependence of the achieved image quality on optimal settings of sequence parameters and anatomical and physiological situations with special emphasis on phase-contrast imaging and other cine-techniques.
